The temperature on
Mercury is so hot that it could melt a tin pan. Mercury is the second
smallest planet in the solar system. Only Pluto is smaller. Mercury is about the
same size as our Moon. It is very close to
the Sun. Mercury travels around
the Sun faster than any other planet. It was named after
Mercury, the swift messenger of the Roman gods.Mercury takes 59 days
to make a rotation but only 88 days to circle the Sun. that means
that there are fewer than 2 days in a year!Mercury can only be
seen from Earth just before sunrise or just after sunset, but not in the
middle of the night, because it always appears near the Sun. Mercury has a very
thin atmosphere. The surface of Mercury
has holes in it where objects such as meteorites and asteroids crashed
into it.
